Door and jambs and jamb-linings pertaining thereto

Abstract: The invention relates to a door consisting of a door sheet and jambs and jamb-linings pertaining thereto, and which are to be fitted in a wall opening, characterized in that said jamb has at least on the side of the pivot axis (X) a continuous bowl-shaped cavity (2) directed towards the door sheet (4) and wherein the concerned edge of the door sheet (4) fits, which bowl-shaped cavity (2) has a radius which is substantially equal to the distance between the centre line of the pivot axis (X) of the door sheet and said edge of the door sheet (4).

Description: This invention relates to a door consisting of a door sheet and jambs and jamb-linings pertaining thereto, and which are to be fitted in a wall opening, the pivot axis of the door sheet being situated on a distance from a first jamb which extends in vertical direction against a first side of the wall opening and comprises a first continuous open recess with a bowl-shaped cross section directed towards the door sheet for receiving a first vertical edge of the door sheet, whereby the radius of the first recess is substantially equal to the distance between the centre line of the pivot axis of the door sheet and the first vertical edge of said door sheet, whereby a first abutment is removably mounted into the continuous open recess, and the door sheet further comprises a second bumper to be received by a second abutment which is removably mounted into said jamb. It has already been proposed to hinge a window or door sheet on one of its vertical edges with its extremity on an arc-shaped cavity of a jamb for a window or a door. Examples of such solutions can be found in the following documents: DE 87 127, DE 27 25 159 and LU 36 870. In US-A-3,827,183 a centre-hung pivot door assembly is disclosed which substantially eliminates the hazard of damage to fingers being caught in the door and which at the same time is weather resistant. The door assembly disclosed in US-A-3,827,183 comprises at least one door pivotally mounted in a door frame, the latter comprising parallel pivot and strike jambs, the door comprising parallel pivot and lock stiles. Along substantially the entire length of the pivot jamb, a concave jamb projection member which projets into the door opening is attached. In the door frame, in closely spaced relation with the jamb projection an arcuate-shaped pivot stile is mounted. A resilient weather seal spans the gap between the pivot stile and the pivot jamb. The space between the jamb projection and the pivot stile always being less than the thickness of human fingers. On the outer edge of the lock stile of the door a resilient, arcuate edge guard is mounted, the width of which is greater than the thickness of human fingers, so that an adult can grasp the door when it is closed. Because of the resilience of the guard, the risk to pinching of the fingers between door and jamb is eliminated. Into the strike jamb a resilient weather strip is mounted which span the gap between the edge guard and the door jamb, to ensure weather resistance. A particular object of the invention is to prescribe a door having a jamb permitting the door to be pivotally mounted on the left or right hand side in the jamb and, if need may be, to make from the door either a two-way door or a one way door. In order to enable this according to the invention, said second abutment alone or said second bumper and said second abutment are made of a flexible material, whereby the second bumper and second abutment comprise a lengthways extending, co-operating concave recess and convex projection to releasably retain the door sheet in the closed position. Another very remarkable object of the invention is to provide means whereby the jamb-linings pertaining to the door and to the jambs are easy to remove and to be put back; the combination of jamb and jamb-linings having, in this respect, to be adaptable to various dimensions to achieve a door structure of large flexibility. It must be possible to compensate for the tolerances in wall finishing observed when mounting the door jambs. Still according to the invention and in view of providing a technically reliable solution for the problem set forth hereinabove concerning the flexibility, said jambs comprise two wings extending laterally with respect to said continuous bowl-shaped cavity for receiving jamb linings, and said jamb-linings comprise a resilient wing which may be clamped between the wings of the jamb. Other details and advantages of the invention will become apparent from the following description of a door consisting of a door sheet and jambs and jamb linings pertaining thereto according to the invention. This description is only given by way of example and does not limit the invention. The reference numerals relate to the annexed figures.

Figure 27 is a cross-section through a bumper according to a variant embodiment to be used in combination with a spherical abutment. Figure 28 shows a section through the aluminium framework used for reinforcing the door sheet. Figure 29 illustrates the problem which could be caused by a lever moment on the pivot axis of the door. For clarity's sake, the hatching in certain components has not be indicated in different figures. The door shown in these figures is a pivoting door, the door sheet, or in some cases both door sheets, of which have to be able to be pivoted in one or in both directions over 90°. An essential object of these doors is that it does not present a.o. the dangerous nut-cracker effect. This results from the combination of the following two characteristics. In such a door, the pivot axis X (indicated in the different figures by a small cross) is situated on a distance of the jamb 1 concerned and this jamb shows a bowl-shaped cavity 2 wherein the bumper 3 or 9 of the door sheet 4 fits and may pivot. To this end, said bowl-shaped cavity 2 has a curvature radius which is substantially equal to the distance between the centre line of the pivot axis X and the inner wall of this cavity. This means therefore that the bumper 3 or 9 of the door sheet 4 pivots purely in this bowl-shaped cavity 2. The danger of objects or fingers getting between door sheet and jamb is therefore out of the question. A bumper 3 has, according to the here most often represented embodiment, in the middle of its curved edge a rounded cavity 3' (see especially figure 22), the role of which will be explained hereinafter. The bumpers which are provided on the side turned away from the hinged side and on the upper side carry the reference 5 (see a.o. figure 23). Such a bumper 5 may show in the middle a rounded cavity 5'. Figure 27 shows a bumper 6 having wider rounded cavities 6'. Figure 25 shows an abutment 7 having a convex side 8 with continuous bulges 8'. Finally, figure 26 shows a particular bumper 9 having a spherical bulge 9'. The bumper 9 with its spherical profile 9' fulfils a well determined function as a variant embodiment of bumper 3. 5. The jambs 1 which form both vertically as horizontally, i.e. above in the door opening, the door casing, consist of profiles 10 showing the already earlier mentioned bowl-shaped cavity 2 (figure 13). In the middle of this cavity 2, there extends a continuous open chamber 11. This chamber includes two lateral grooves 12. The continuous open chamber 11 with its grooves 12 serves for receiving abutments with various sections. They are described hereinafter into detail. The various pivot shaft components are also fixed in the continuous open chamber 11. In the profile 10, there is still a further continuous open chamber 13 intended a.o. for receiving corner connection pieces. Referring a.o. to figures 1, 2, 5, 6 7 and 21, it will be seen that use is made here of a tubular abutment 14 with ribs 14'. Such an abutment is made of a flexible and resilient material which is snapped over the entire length into the continuous open chamber 11. When the door sheet is in its closed position, as shown a.o. in figures 1 and 2, the tubular abutment 14 fits into the rounded cavity 3' of the bumper 3. On the side turned away from the hinge side, different solutions may be applied a.o. depending on the fact that the door is a two-way door or a one-way door. In order to solve this problem without having to change neither the door sheet nor the jambs, use is made of abutments of different types. A series of abutments are shown in figures 14 to 18. The abutments 16 according to figures 14 and 15 are wedge-shaped abutments which are each provided with a central continuous bulge 17. All abutments have two continuous wings 18 with hook-shaped projections 18' for fitting them into grooves 12 provided in the inner wall of the continuous open chamber 11. The wedge-shaped abutment 16 according to figure 14 is intended for letting the door panel pass in both directions. The wedge-shaped abutment 16 according to figure 15 is provided with a resilient lip 19 for stopping the door sheet so that such a wedge-shaped abutment can only be present on a one-way door. The abutments 20, according to figures 16 and 22, are spherical abutments since the bulge 17 was here replaced by a continuous rounding 21. Here the difference can also be seen between the spherical abutment according to figure 16, intended for a two-way door, and the abutment according to figure 17 which is equipped with a resilient lip 19 of the type which is present in figure 15. The just described abutments 16 are designed for cooperating with bumpers of the type according to figure 23 (bumper 5). The abutments 20 are designed for cooperating with bumpers of the type according to figure 27 (bumper 6). It is immediately clear that by making use of abutments according to figures 14 or 16, the possibility is created to turn the door sheet in both directions while with abutments according to figures 15 or 17, the door can only be opened in one direction. It is therefore also immediately clear that by fixing an abutment with resilient lip in a certain direction in the jamb profile, the door sheet can be moved in the first or on the contrary in the other direction. Figure 3 relates to a door wherein the door sheet is equipped on the top with an abutment 16 of the type shown by figure 15. Such a door is on the top weather tight whilst small brushes 22 seal it off underneath. A particular type of bumper is shown by figure 26. The abutment 25 is of the type to which the wedge-shaped abutments pertain, with this difference that the arcuated groove 25' fulfils here the function of either the bulge 17 or the continuous rounding 21. In order to avoid wear of the spherical bulge 9', the edges 26 of the continuous open chamber 11 which are directed towards one another can be adapted to the rounding of the spherical bulge 9' of the bumper 9. The deformation of the flexible and deformable bumper 9 is not shown in the figures. The magnitude of this deformation can however be derived from the presence of arrows which indicate this deformation. From the here given description of the different abutments and the bumpers cooperating therewith, it can be deduced which function is fulfilled by these components, both as to the weather tightness and as to blocking the door sheet in the closed position. As to these components, reference can further be made to different figures such as figure 6 which shows how an abutment is pushed or snapped into a jamb. Figure 5 shows, on the contrary, how the tubular abutment 14 is fixed into the continuous open chamber 11 of the jamb. Figure 6 illustrates schematically the positions wherein a door sheet which can be turned over 180° can be pivoted with respect to a jamb. Figure 7 shows how a tubular abutment 14 can be deformed in two directions when a bumper 3 is displaced along such an abutment. When two door sheets are made to cooperate with one another so as to form a so-called double door, it is sufficient to provide the edges of the door sheets which are directed towards one another with cooperating abutments and bumpers as can be seen in figure 8. In several figures, for example in figures 1, and 13, it can be noticed clearly that the cross-section of the continuous open chamber 11 fulfils several functions. The walls (a) of the continuous open chamber 11 are directed for example under such an angle that the head of a screw 26a, which goes through the body of the jamb profile, is precisely adjusted to the slope of the sides. The jambs extending around the perimetry (at least along three sides) show further two parallel wings 27 and 28 between which jamb-linings 29 can be clamped. These jamb-linings are formed of aluminium profiles with a curved resilient wing 30 thanks to which the jamb-lining itself is stuck between the wings 27 and 28 of the jamb. Further, the jamb-lining has substantially opposite the resilient wing 30, a flat strip 31 for maintaining it under pressure against the inner side of wing 28. The semi-circular strips 32 of the jamb-lining profiles close off on both sides of the jamb the space between the wing 28 and the wall 33. A sealing strip seals this space hermetically. The here described jamb-linings 29 are those which can be seen in different figures. Figure 20, however, relates to a variant embodiment wherein the jamb-lining 29' has a rectilinear strip 32' which fulfils the same function as the semi-circular strips 32. It is clear that several other profiles may be appropriate for forming the jamb-linings. It is immediately clear that jamb-linings according to the here described examples can be adapted to all kinds of wall thicknesses and to compensate for the tolerances related thereto. The invention also relates to the structure of the door sheet itself. This original structure was not only invented for counteracting any deformability of the door sheet. Due to the original concept of the door itself with its two vertical edges and the upper horizontal edge, provided with bumpers, the door sheet has to cooperate purely with the different abutments described earlier in this application. The door sheet has further to show such a strong inner structure that the pivot of the hinge itself offers resistance when in the open door an important lever moment is generated which can occur when a pressure is exerted onto the door sheet and the door sheet pushes in the zone to which point P (figure 29) belongs against the wing 28 of the jamb 1. The lever moment which acts upon the hinge and door sheet structure is considerable in view of the position of the pivot axis X with respect to said point P. To obviate this, the door sheet is equipped internally with an aluminium framework formed of hollow profiles 35 which can be seen a.o. in figures 11 and 28. In the corners, the connection between transverse and longitudinal profiles is achieved by making use, along the inner edge, of a connection corner 36. The section of the aluminium profiles 35 is shown clearly in figure 28. It is a strong hollow profile with recesses 38 wherein the taps provided on the bumpers can be snapped. Referring to figure 9, it can first of all be seen how jambs 1 are mutually connected by connecting pieces 39 by screwing tighter pulling bolts 40. The angle bar connection profile 37 of the upper hinge is pushed in the corner connection between two jambs (figure 9). This angle bar can be seen in section in figure 17. The cross-section of this angle bar corresponds partially to the cross-section of the continuous open chamber 11 of the jamb and is therefore clamped herein by means of small socket head screws 41. The rectangular component 42 is also a part of the angle bar 37. Against this component caught in the aluminium profile 35, there is screwed an attachment block 43 for the pivot of the door by making use of the connection bolt 44 which goes through both components 42 and 43. The component 43 is attached, on the top, to the aluminium profile 35 by means of screws 45. The pivot of the hinge is mounted in the component 42. The portion 42' of the component 42 comprises the means known per se for making the door sheet return to its zero position and the means for allowing the door sheet to be maintained both in the entirely open position and in all intermediate positions. The door sheet 4 is thus hung up in chamber 11 of the jamb 1 by means of the angle bar attachment pieces 37 provided on the pivoting upper and lower hinges which are fixed in their turn by means of attachment blocks 43 in the upper and lower corner of the door sheet. From the hereabove given description of the door, the door sheet and the jambs and jamb-linings pertaining thereto according to the invention, the following clear advantages of these structures become apparent : a) the mutual interchangeability of the various door abutments which allows to change from a one-way door to a two-way door and vice versa ; b) the possibility of changing the hinge side of the door ; c) the fact that no latch has to be installed since the abutment construction makes this redundant ; d) the construction of the reinforced door sheet and the concept of the tubular profile for glass doors which houses the hinge, whereby the moment in case of overloading as a result of the lever effect is compensated for ; e) the safety offered by the bowl-shaped profile of the jambs whereby the dangerous nut-cracker effect is avoided especially when considering the fingers of children. It is clear that the invention is not limited to the hereabove described embodiment and that modifications can be applied thereto in as far as they fall within the scope of the claims annexed hereto.
